DUMP-CAR.

Specification of Letters Patent.

Patented (Pct. 1%,1909.

Application filed. January 18, 1909. Serial No. 472,787.

To all whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Dump-Cars, of which thefollowing is a specification.

My invention relates to improvements in dump cars.

The object of my invention is to provide an improved construction ofdump car in which the discharge opening may be of greater lengthlongitudinally than the clear space between the car wheels or car wheelaxles.

My invention consists in the means I employ to practically accomplishthis object or result. That is to say, it consists in connection with adump car body, the bottom of which preferably has inclined sides andends and is provided with a discharge opening of greater lengthlongitudinally than the clear space between the car wheels, of threedoors for closing said opening, two of which are transversely hinged atthe transverse or end edges of the discharge opening, and whichpartially close said opening, and an intermediate longitudinally hingeddoor which is hinged at one edge to one of the longitudinal edges ofsaid opening, and which middle or intermediate door extends across theopening from side to side. The longitudinally hinged intermediate doormay, if desired, be split transversely of the car into two or moremembers or sections for convenience of manufacture.

My invention further consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described.

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation of a dump car embodying my invention. Fig. 2 is avertical cross section on line 22 of Fig. 1 and Fig. 3 is a plan view.

In the drawing, 1 represents a dump car body, the bottom of which ispreferably furnished with inclined sides 2, and inclined ends 3 and witha discharge opening 1, and of greater length longitudinally than theclear space between the car wheels 5 or their axles 6. This dischargeopening 4: is closed by three doors, two transverse hinged doors 7, 7,each connected to the car body by hinges 8 at one of the outertransverse or end edges 9 of the discharge opening 41. These twotransversely hinged doors 7, 7, partially close the discharge opening ofthe dump car. The remaining portion of the discharge opening 4: isclosed by a longitudinally hinged door 10, connected-by hinges 11 at oneof its ends 12 with the car body adjacent to one of the longitudinaledges 13 of the discharge opening 4. This longitudinally hingedintermediate door 10 extends transversely across the discharge openingfrom side to side and cooperates with the two transversely hinged doors7, 7 inclosing the discharge opening. The intermediate longitudinallyhin ed door 10 may, if desired, be split on a line transverse of thecar, into two or more separate sections or members 14: for convenienceof manufacture and manipulation. The transversely hinged end doors 7, 7,and the longitudinally hinged intermediate door 10 may be operated oropened and closed by any suitable door operating mechanism. The dooroperating mechanism which I prefer to employ comprises two transverselyextending operating shafts 15, each furnished with winding drums 16 andchains or connections 17, 18 extending to the free or swinging ends ofthe transversely hinged doors 7, 7 and of the intermediatelongitudinally hinged door 10.

I claim 1. In a dump car, the combination with a car body having adischarge opening of greater length than the clear space between the carwheels, of two transversely hinged doors partially closing saiddischarge opening, and an intermediate longitudinally hinged door hingedat one longitudinal edge of said discharge opening and extending acrossthe same to the other edge thereof, and closing the intermediate portionof said opening, substantially as specified.

'2. In a dump car, the combination with a car body having a dischargeopening of greater length than the clear space between the car wheels,of two transversely hinged doors partially closing said dischargeopening, and an intermediate longitudinally hinged door hinged at onelongitudinal edge of said discharge opening and extending across thesame to the other edge thereof and closing the intermediate portion ofsaid opening, and operatin mechanism for opening and closing said doors,substantially as specified.

3. In a dump car, the combination with a car body having a dischargeopening of greater length than the clear space between the car wheels,of two transversely hinged doors partially closing said discharge opening, and an intermediate longitudinally hinged door hinged at onelongitudinal edge of said discharge opening and extending across thesame to the other edge thereof and closing the intermediate portion ofsaid opening, said intermediate door being split into two members, bothof which are hinged at one and the same longitudinal edge of saiddischarge opening, and both of which extend entirely across saiddischarge opening from side to side, substantially as specified.

4t. In a dump car, the combination with a car body having a dischargeopening in the bottom thereof, of two doors partially closing saidopening hinged to the car body at opposite parallel edges of saidopening, and an intermediate door extending entirely across said openingand hinged to the car body at an edge of said opening which is at rightangles to the hinged edges of said two first mentioned doors,substantially as specified.

5. In a dump car, the combination with a car body having a bottomfurnished with a discharge opening, of two doors partially closing saidopening hinged to the car body at opposite parallel edges of saidopening, an intermediate door extending entirely across said opening andhinged to the car body at right angles to said first mentioned doors,substantially as specified.

6. In a dump car, the combination with a car body having a dischargeopening, of two transversely hinged doors, each partially closing saidopening and an intermediate longitudinally hinged. door extendingentirely across said discharge opening, substant-ially as specified.
